Recording method and device, terminal and storage medium

Abstract

This application provides a recording method. The recording method includes judging whether there is a portrait in one or more frames of images captured by the camera of the terminal; if there is, recording through at least three microphones of the terminal to obtain at least three first audio signals; according to the at least The three first audio signals and the beam angle determined by the position of the portrait in the captured image are used to denoise at least three of the first audio signals; and synthesizing the denoised at least three first audio signals audio signal to generate a stereo audio signal. In the recording method according to the embodiment of the present application, the at least three first audio signals are denoised by using at least three of the first audio signals and the beam angle determined by the position of the portrait in the captured image, and the sound can be The ambient noise outside the beam angle where the source is located is removed, and the recording effect is better. The present application also provides a recording device, a terminal and a non-volatile computer-readable storage medium.

Description

technical field [0001] The present application relates to the technical field of recording, and in particular to a recording method, a recording device, a terminal and a non-volatile computer storage medium. Background technique [0002] Stereo refers to sound with a stereo effect. In order to achieve stereo recording, the terminal generally records through multiple microphones in different positions to synthesize stereo audio signals. However, not only the sound of the sound source is recorded during recording, but also the sound source The surrounding environmental noise is also recorded, resulting in poor recording effect. Contents of the invention [0003] To this end, the embodiments of the present application provide a recording method, a recording device, a terminal and a non-volatile computer storage medium. [0004] The recording method in the embodiment of the present application includes judging whether there is a portrait in one or more frames of captured imag...

[0002] Stereo refers to sound with a stereo effect. In order to achieve stereo recording, the terminal generally records through multiple microphones in different positions to synthesize stereo audio signals. However, during recording, not only the sound of the sound source is recorded, but also the sound source The surrounding environmental noise is recorded together, resulting in poor recording effect
